To all whom it may Concern:

Be it known that` l, Join: dhunnnotn a resident of New Eagle, in thecountv of liVashington and State ot' Pennsylvania7 have invented a newand useful lninrovement in Apparatus for Cutting Glass. ot which the'followin is a full, clear. and ein act description, reference being;had lo the accoininin-ying drawings, forming' part of thisspecification, in Which.-

Figure l a plan vienv partly broken away of apparatus embodying in vinvenupper portion of the cutting igahle and illustrating the action otthe cutting' and breaker devices;

Fig. 9 is a detail sectional vien' of one of the adjustahle pallets;

l() is a section onthe line X-Li ot Fig. 9;

Fig. 11 is perspective view of one of the adjustable pallets;

Fig. l2 is a perspective vieiv of one of the cutting table strips;

Fig. 13 is a sectional View ot the stackingl chair; and

Fig. 14 is a section on the line Xl`V-`XlV of Fig. 13.

My invention has relation to glass-cutting apparatus, and moreparticularly to a inachine or apparatus for cutting or'trinnning theedges of tf {lass sheets to a 'predetermined size. Une objectief myinvention is te provide an apparatus or machine ottliis char-` acterwhich will reduce the manual labor required and will enable theoilierations to he carried on much more rapidly and eilin-iently. Afurther object ci my invention is to provide a machine or apparfnxns ofthis charaeten in 'which mechanical means oi simple and e'llfcrlivecharrulicr are Aprovided touzmcurately and uniformly' breaking ofi thetrim or cull portions ot the sheets after they have been scored by thecuttingl tool.

Other objects of my invention have relation to the construction andarrniif'einent of parts whereby adjustment of the machine to sheets otdiiierent Widths niaj; he readily,r elii'ected andv for 'facilitatingthe general operationoi the machine.

' lily invention will ne best understood hy reference to theaccnn'qmnying drawingsv in which l have shown a preferred. embodimentthereo'll and which will lnon' he de4H scribed. it being promised.however, that various changes may ou made in the details ofemistruetion7 arrangement and eoinhi a tion ot' parts, withoutdepart-inzg7 from the spirit and scope of in v invention as defined inthe appended claims.

ln these drawings. the numeral designates the 'traine of the machinewhich supports the inain table 'rlhe latter is cut awa;v lonnitudinall;Yto receive tlnnein the cutting; talilc. which coi'isists of an endless-1niovinn conveyor. 'l'h may he eonveniently i (Fig. 8l to which aresecured a plus. lity of transverse strips or cleats Fn Athe latter beingarrangeil to lie closely' side side at the upper working portion of thetable to torni a supporting surtaee for the gli; sheets to he cut ortrimmed. ller reaaons 'which will hereinat'tor appear, the Work,n ingsurface of the table should have porn tions at difierent levels. `uorthis purpose, one end portionof the 'ps is reducev'l in thicknesa at itsupper .fadet as indicated at 6. This is leest shown in detail in Fig.l2, although indicated in other views.

Certain of the strips or cleats 5 are pian vided 'with the transverselyA:ulinatalile pal-- lets 7. which are seated in tr: or guides 850i' suchleaiis, and can transversel" ierein or less portion oi t. Y j reduced*portion of the cleats. lf iese na are secured in desired adjustment nyany' suita'lnle ineens, euch the Screws; 97, inch torined hy the tivoendless helts 4In the machine shown in the drawings, there is providedan electric motor 14, driving a gear wheel 15, connected by a belt 16with I. one of the rolls 17 upon which the table is carried.

18 designates a` supporting barwhich extends transversely across theclrltting -table and which forms a carrier for-a number of parts now tobe described. 19 and 20 designate two holding-down wheels, which arejournaled on levers 21, which are pivoted at 22 to thel respectivebrael'ets 23 and 24. These brackets are provided with liookshaped upperportions which engage the transverse support 18 in the manner best shownin Fig. 4, and are adjustably secured on said support by means of theset screws 25. The pivots for the levers 21 are shown as formedbytrunnion screws, as best shown in Figs. 3 and 5. Each of the levers 21has va tail extension 21a, to which israttached a 'tension spring 26,whereby the desired amount of pressure may be exerted by said wheels. Anadjustable stop 27 is also provided for controlling and limiting suchpressure.

v inthe slot 38 of the bracket 23. The pivots for the block37 preferablyconsist of trunnion 'screws 39.

4The cross member 33 can 'be adjusted to any desired position on the rod34', and the transverse distance between the two wheels 28 may be variedby loosening the set screws 32 and rotating the arms 30 on the stud 31,through an angle of 180, thereby bringing the two wheels closertogether. The relation of the wheels 28 to the wheels 19 and 20 is suchthat the glass sheet being cut will be engaged by `the wheels28 beforeit leaves the, wheels 19 and 20.

The numeral 40 designates a cutting tool' arm of a bracket 44, which isadjustably secured on the support 18, by means of a set screw 45. Inuse, the position of the cutter is adjusted so that it will be. adjacentto the ends ofthe adjustable pallets 7, substantially as shown in Fig.8.

The numeral 46 designates a breaker wheel, preferably of wood fiber orsome nonmetallic material, and which is j ournaled to a stud 47, securedto an arm 48, which is transversely adjustable on the pin or stud 49, asbest shown in Fig. 6. The pin or stud 49 is carried by a block 50,which4 is adjustable longitudinally 'on the rod 51. The rod 51 issecured at end portion in a block 52, which is trunnioned at 53 in abracket 54, adjustably secured to the support Q18 by means of the setscrew 55 (see Fig. 2). 56 is a weight which is adjustably mounted on thearm 57, .which is, in turn, adjustably mounted on the rod 51, (see Fig.l2) and by means of which the necessary pressure is applied to thewheel46.

58 designates a conveyer, on to which the cut and trimmed sheets aredelivered from the end of the cutting table, the sheets falling ontothis conveyer 58, through the opening 59'in the table 3. This conveyor58 may be driven in any suitable manner, as by a belt 60 from a beltwheel 61, driven by the motor 14. Separate driving means may,- however7`be ,employed .for this conveyer, which should be driuen at a higherrate of speed than that of the cutting table. This conveyer ispreferably inclined upwardly from its receiving to its discharge end, asshown in Fig. 2, and is arranged to deliver' the cut and trimmed sheetson to a stacking chair. The latter consists of a base member 62. whichis carried on a yoke 63 (see Figs. 2, 13 and 14) provided with acalibrated supporting spring 64, one end of which is provided with anadjusting device 65, whereby the tension of the spring may be variedaccording to the weight to be carried. This weight will necessarilydepend upon the thickness and size of the cut and trimmed sheets, which.are delivered to the chair. The chair is provided above the baseportion with a rearwardly and downwardly inclined plate. 66, which mayconsist of a glass sheet. The chair also has an upwardly and rearwardlyinclined back portion 67 The upward inclination of the conveyer 58 llO ''sisting of an angle 68, having a facing 69, "which may consist of aglass strip. vThe' .which acts upon the sui-tace ofthe sheet ust'--zinadva'nce of the cutting tool. to'

p urpose oi-this facingis to provide as rnootb polished surface fortheedges of the glass sheets and to prevent wear upon the angle.

The numeral 70 designates a lubricant reservoir which supplies the usualwiper 71,

The operation is -as 'olloivsz The sheets lo be cuter trimmed are placedupon the receiving end portion 'of the table 3 and are fed in succession'by an operator to the movi ing'eutting table., eacli"sli ee tbeingplaced" between two of tlie cleats-'13.
